Theengs Bridge BLE to MQTT gateway supports Home Assistant, OpenHAB, Jeedom, NodeRed, and more

Theengs Bridge

The Theengs Bridge is a new WiFi & Ethernet BLE to MQTT gateway running the open-source OpenMQTTGateway firmware, compatible with a range of sensors, and supporting Home Assistant, OpenHAB, Jeedom, NodeRed, and other MQTT-compatible systems. It follows the Theengs Plug smart socket introduced at the beginning of the board with many of the same features (minus the socket part…) but adds Ethernet and an external antenna for improved range, and improves modularity with a Grove I2C connector and mounting holes for a LoRa-E5-based Grove module and a prototyping area where you can solder your own circuitry with DIP components. Theengs Bridge specifications: Wireless module MCU – ESP32 microcontroller with WiFi and Bluetooth Storage – 8MB flash PCB antenna and u.FL antenna connector Connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth LE with 6dBi 50Ohm external antenna Optional LoRa module via Grove I2C connector MQTT protocol Expansion – […]

ESP32 OpenMQTTGateway smart plug acts as an BLE MQTT gateway and a power meter

ESP32 BLE Gateway Power Meter

The Theengs Plug ESP32 smart plug runs OpenMQTTGateway firmware to serve as a BLE MQTT gateway and power meter compatible with Home Assistant, Homebridge, OpenHAB, DomoticZ, FHEM, Jeedom, NodeRed, AWS, and any MQTT-compatible IoT or Smart Home system. While the Matter standard should improve interoperability between Smart Home frameworks over time, there are still millions of devices already produced that are not Matter compatible, and the Theengs Plug aims to at least partially address this issue by helping users reduce the number of hubs required and have only one that supports different ecosystems. Theengs Plug hardware specifications: Microcontroller – ESP32 dual-core wireless MCU with 2.4 GHz WiFi and Bluetooth LE connectivity Network Protocol – MQTT Power Supply – 100-120VAC, 60Hz, up to 15A Dimensions – 103 x 61 x 34.6mm Temperature Range – Operating: 0ºC ~ 40ºC; storage: -10°C ~ 50°C Humidity – 0%~95% (no condensation) Certification – UL Some […]

433 MHz is not dead! Using an ESP32 board with LoRa module to talk to 433 MHz sensors

RTL 433 to MQTT ESP32

CNXSoft: This is a guest post by Florian Robert (1technophile) of the OpenMQTTGateway project about using a 433 MHz LoRa transceiver on an ESP32 board for home automation, specifically to talk to 433 MHz sensors Everyone is talking about Matter, Bluetooth, Zigbee, and Zwave, but before these complex communication technologies, we had one simple, robust one that our sensors and devices used to leverage: 433MHz. It may be too simplistic to talk about 433 MHz as a technology as there are different and various usages of this frequency. You can find it being used in numerous devices around your home, from your outdoor temperature sensors, and security sensors to the tire pressure sensors in your car. If we want to be specific, we can talk about the different radio frequencies (433 MHz, 915MHz, 868MHz, 315MHz, or 350MHz) and signal modulations OOK, ASK, FSK that we encounter behind the keyword 433MHz.

Sonoff ZBDongle-E specifications: Wireless MCU – Silicon Labs EFR32MG21 Arm Cortex-M33 multiprotocol wireless MCU @ 80 MHz with 64KB RAM, 768KB flash, +20 dBm 802.15.4 radio for Zigbee 3.0 and Thread support, and as well as a Bluetooth 5.1 Low Energy radio Connectivity – Zigbee 3.0 with SMA antenna connector, +20 dBm output power Host interface – USB port with CH9102F USB to TTL chip Expansion – 7-pin IO header with programming pins Misc – Boot and reset buttons, Zigbee LED, Power LED Power Supply – 5V/100mA via USB port, […]

Theengs open-source tools to decode BLE sensors work on ESP32, Raspberry Pi, Android phone, etc…

Theengs

Theengs is a manufacturer agnostic open-source set of tools to decode BLE sensors and integrate those into smart home and IoT solutions such as Home Assistant with notably support for autodiscovery to automatically create the sensor. Theengs can be installed on various hardware from ESP32 to an Android phone or a Raspberry Pi SBC, and the solution currently supports close to forty BLE sensors from various companies including Xiaomi, Honeywell, and RuuviTag.   There are six components: The Theengs Decoder library developed in C++ for portability and translating data from sensors into human-readable data using the JSON format. The Python-based Theengs Gateway acting as a BLE to MQTT bridge for Home Assistant, OpenHAB, and NodeRED integration. It relies on the Theengs Decoder library and publishes the sensors broadcasted BLE information to an MQTT broker. The OpenMQTTGateway is also BLE to MQTT bridge, but instead of targetting Linux-capable hardware like Raspberry […]
